1, LED lamp itself characteristic--the unidirectional light, not the diffuse light, ensure that light efficiency. 2, the electric lamp has LED to the unique second optical design, the light of the street lamps will LED to illuminate the area for lighting, further improve the illumination efficiency, and the energy-saving objective. 3, LED light source efficiency now has 110-130 lm/W, and very big development space, the theoretical value of 250 lm/W. And high-pressure sodium lamp is luminous efficiency with power increase just increased, so overall efficacy LED street light than high pressure sodium is strong; (the overall efficacy is the theory, in fact 250 W above high pressure sodium efficiency higher than LED). 4, the light of the street lamps LED show color sex than high pressure sodium high many, high-pressure sodium lamp show color index only 23 or so, and LED street light show ?
